To all whom it may concern.:-

Be it known that I, ROLLIN H. ARNOLD, of the city of Rochester, State ofNew York, have invented certain new and useful Improvements inBook-Supports, of which the following is a description, reference beinghad to the accompanying drawings, forming part of this specification.

My invention relates to book supports which are adjustable with respectto their supporting tables, so as to be able to be swung into a numberof positions.

In the drawings, Figure l is a perspective view of my invention appliedto a'table, showing by dotted lines another position. Fig. 2 shows theslides removed in perspective; and Fig. 3 is a vertical section on theline w y, Fig. 2.

A, is a table; B, a shelf under the same.

C, is the book support, provided with ways, (l, d, fixed to theunderside thereof, which engage a base, e, at its edges. The base, e, ispivoted at, f, to the shelf, B, so as to rotate upon said pivot, andafter being rotated into the proper position, the book support is slidoutward upon its ways, d, d, its motion being limited by a peg, h, orh', engaging the closed end of the slot gor g', respectively, accordingto the direction in which it is slid. The base, e, is provided withanother slot, Z, in which is pivotcd a latch, m, which vibrateshorizontally through a short arc, and which has a notch, fn, whichengages a peg, lo, which latter projects downward from, O. The latch ispressed forward by a spring, p, placed in a recess behind the latch, asshown. This latch serves to lock the slide, C, when at its centralposition, .with reference to the table. The

`latch pivot is shown at r.

.ment of said member C relative to said base piece.

2. The book support, C, provided with ways, d, d', and pins, h, h', andle, in combination with the base, e, adapted to engage said ways at itsedges, and provided with slots, g, g and Z, and the pivotcd latch, m,all substantially as described.
